SUCTION-OPERATED LIGUIDDISPLACING APPARATS.

Application tiled May 11, 1925. `Serial No. 29,477.

My invention relates to apparatus wherein liquid is caused o be moved 'from one location to another hy the exertion of suction in the receptacle to which the liquid is to be supplied: and. more particularly. though not exclusively, to such a type of apparatus provided for evacuating the oil casing; of au- .tomobiles and, morev especially. the crank cases thereof, where change of oil therein is desired; and particularly where tbc suction. for effecting the discharge of the liquid into the receiver of the apparatus. is produced by compressed air passing through an ejector the suction inlet ofwhich communicates with the receiver for the liquid.

My primary objects are to provide in connection with the exhaust for the suction-producin fluid employed in an apparatus of the c aracter stated, means whereby the noise which would be produced if the fluid exhausted directly to the atmosphere, shall be mufiied; and to provide for the utilization of the exhausting fluid-pressure as the means of operating a movable, preferably rotatable, member preferably bearing any suitable advertising matter. As I have devised my improvements for use more particularly in a cra-nk-casesevacuating apparatus such as .that disclosed in my pending application for U. S. Letters Patent Serial No. 13,819 filed March 7 1925, I have chosen to illustrate it in such an apparatus, but not, however, with the intention of limiting its use to such an apparatus.

Referring to the accompanying drawings:-

Figure 1 is a view in vertical sectional elevationofa portion of an apparatus like that disclosed in my said application, and to which my present improvements are applied, a -portion ofthe upper part of the apparatus being broken away. Fig. 2 is an enlarged view in elevation, partly sectionahof a device embodying my improvements showing the mannerA of mounting my device upon the suctionproducing Huid-pressure exhaust-pipe of the evacuating apparatus to which it is applied. Fig. 3 is a View insectional lelevation of the top portion of the receptacle into which the oily is sdrawn, Vshowing the ejector device mounted therein for producing suction in the receptacle; and Fig. 4, a section taken at the line 4 4 on Fig. 2 and viewed in the direction of the arrows.

In explanation ofthe illustrated apparatus as to tho-'e features forming the subject of my said pending application, it. may be stated that 1t) represents a receptacle for receivingY the oil.. this receptacle being provided in itsA top with an ejector-device 11 supplied withv compressed air from any suitable source,

through a pipe 12.- t'hc suction-inlet of the ejector being repre ented at 13 and opening into the upper portion of the receptacle 10,

surrounded by a pipe 15 which opens atits* upper end into the upper part of the receptacle 10 and at its lower end connects, by a passage 16 in the bottom of the receptacle 10, with a pipe 17 which leads to a flexible hose-line (not shown)` preferably equipped with a fitting, as set forth in said application. to facilitate its connection with the lower drain openings of crank-cases to be evacuated, and to which the suction created in the receptacle 10 is applied through the pipe.15, passage 16, pipe 17 and hose line referred to, to transfer the oil in the crankcase to the receptacle 10. The air pipe 12 is shown as leading outwardly from the standard 18 supporting the receptacle 10, this being in accordance with said application wherein the pipe 12 is connected with a valve v(not shown) and located exterior of the standard 18, for controlling the supplying of air to the pipe 12, the valve connecting at its inlet with a pipe 12a which w/ould lead from the source of compressed-air for supplying the pipe 12.

In accordance with my present invention, I provide a motor positioned to be operated byV the fluid-pressureexhausting from the pipe 14s and serving not only to inutile the exhausting pressure, but also` to operate an advertising-bearing member carried by the rotor of the motor whereby the member is rotated. to attract attention, when the ejector device 11 is operating.

The construction .of tmotorshown comprises a pair of di-ai'netrically disposed pipes 1t) carried by, and extending relatively outwardly from, a cap '20 carried by the pipe 14, the inner ends of the pipes 19 communicating with the interior of the pipe 14. The outer ends of the pipes 19 are somewhat flattened vertically and slightly deflected, as

iin

shown at 21 whereby the fluid ressure issuing therefrom issues in jets ischarging somewhat tangentially. The rotor of the motor is represented at 22 and is shown as in the form of a hollow sphere through an opening 23 in the bottom of which, provided with a bearing sleeve 24, the pipe 14 upwardly projects to a point slightly above the center of the rotor. The upper part of the rotor is provided with a socket-bearing 25 adapted to hear upon a point-bearing 213 provided on the upper end of a rod 26 secured to, and projecting upwardly from, the cap 2t). whereby the rotor is freely rotatable. The rotor is provided about its inner surface with a circular series of vanes 27 positioned for impingement thcreagainst of the Huid-pressure discharging from the pipes 1t). to etl'ect rotation of the rotor 22, the fluid-pressure discharging from the rotor through a series of relatively small apertures 28 in the bottom portion thereof whereby the noise ot the exhaust is muled.

'lhe sign-bearing member referred to is represented at 29 and is shown in the form ot' a triangular plate secured at an apex thereof in an ornamental head 30 rigidlyV secured iii an opening 31 in the top of the rotor 22 to rotate therewith and which head is shown as containing the socket-bearing 25.

lVhile I have illustrated and described a particular construction embodying my 1nvention, I do not wish to be understood as intending to limit it thereto as the same may be variously modified and altered without departing from the spirit of my invention.

'hat I claim as new, and desire to secure by Letters Patent, is:

l. In a liquid displacing apparatus, the combination of a receptacle for receiving the liquid, means for producing flow of liquid to the receptacle and involving in its operation the exhausting of fluid under pressure, a fluid-pressure-driven motor associated with said receptacle and in communication with the exhausting fluid, and a display device actuated by said motor.

` 2. In a liquid displacing apparatus, the combination of a receptacle for receiving the liquid, Huid-pressure ejector nieanslfor discharging the liquid into said receptacle and comprising an exhaust pipe extending upwardly from said receptacle, and a fluidpiessiii'e .li'i\'en motor mounted on the upper end ot' said pipe and in communication therewith. f

3. In a liquid displacing apparatus, the combination of a receptacle for receiving the liquid, means for producing flow of liquid to the receptacle and involving in its operation the exhausting of fluid under pressure, an exhaust pipe extending upwardly from said receptacle and through which said exhausting fluid discharges, and
